would you get better performance by buying two, two channel mains powered amplifiers to give you your target 100W into 4ohms?
I wouldn't pay to down convert to 12Vdc, to up convert to ~30Vac, to convert back to ~40Vdc

I'm a car audio fan and since I come on this forum I plan to install a setup in my living room.

I already have the enclosures for witch I have posted a thread.


I need advise for the speakers choice.

My amplifier is an Orion 8004 and the head unit an Eclipse CD7000.

To power this setup I need a power supply. But as I said I dont have any knowledge about PS and I need help. I found this one (Omron) and I want to know if it is appropriate.
